If this patch does not work check the properties of your audio codecs. Open your Sound and Audio Devices in the Control Panel and got to: Hardware -> Audio Codecs -> Properties. Make sure the Fraunhofer IIS MPEG Layer-3 Codec is set to a priority other than 1 (like 10). If not, then remove it and restart. Then open WMFADist.exe on CD1 of NOLF2 and that will reinstall the codec. (This solves about 90% of the problems in the game...).
